Alfa AWUS036NHR with RTL8188RU chipset

Hi there,

i just bought an Alfa AWUS036NHR for testing.
It runs with the rtl8192cu driver.
I have a question because sometimes the wireless adapter dont shows any networks no longer. I have to reload the module an then its showing some networks.

In dmesg it shows:

[  262.219575] ADDRCONF(NETDEV_UP): wlan1: link is not ready
[  269.770133] ADDRCONF(NETDEV_UP): wlan1: link is not ready
[  270.947047] ADDRCONF(NETDEV_UP): wlan1: link is not ready

For any further output please let me know.

What kernel? There are some problems with kernels prior to 3.1 in connecting to 802.11n networks, and also a problem in clearing the keys. Both of these problems are fixed in the latest compat-wireless.

What kernel? There are some problems with kernels prior to 3.1 in connecting to 802.11n networks, and also a problem in clearing the keys. Both of these problems are fixed in the latest compat-wireless.

Larry

Kernel is Linux C1 3.1.0-rc6linux-next1.01-next-20110919 #1 SMP Mon Sep 19 14:23:56 CEST 2011 x86_64 x86_64 x86_64 GNU/Linux I tried to apply the latest compat-wireless but errors are the same.

Chiefdome

I tried at least wireless-next but the adapter isn't showing up. Where to get more log files and stuff?
Isnt this adapter good supported by the rtl8192cu driver or where is the problem?

For the mainline kernel to work with 802.11n-only APs and to reconnect after an initial try, your kernel needs the following patches:

Both of these are in wireless-testing, and were just merged into the mainline kernel. In addition, they were merged with the 3.0 stable tree today.

Both should be in wireless-next, but as I recall, you were not able to test with that tree.

With the updated mainline kernel, the link is stable and performance is acceptible with netperf TCP_STREAM (TX) at 20.5 +/- 4.8 Mbps and TCP_MAERTS (RX) of 21.7 +/- 3.8 Mbps. These numbers are not spectacular, but they will do.

I tried the latest git repo from
git://git.infradead.org/users/linville/wireless-next.
Same story here.
After disconnecting to the network, I have to reload the module only then networks are seen.

I just cloned the wireless-next tree. The two patches mentioned in my previous Email are included.

Please run the following command sequence and send us the dmesg output after your failure occurs:

modprobe -rv rtl8192cu
modprobe -v rtlwifi debug=3
modprobe -v rtl8192cu

The first thing I notice is that you apparently do not have CRDA installed. A second thing is that the interface never comes up. As long as it remains down, it can never connect. How are you connecting? I'm using NetworkManager.

As you notice, this connection uses the CCMP algorithm, i.e. it is with WPA2-AES. It is also an 802.11n. Just to test, I switched the AP to run only at 802.11g rates. That also worked.

I need to know more about your setup. What AP and how is it configured? How do you control the wireless connection?

The AP showen above is configured as you say as an 802.11bgn device. The wireless connection is controlled by wicd.

I just reviewed our entire correspondence on this issue. I could not find where you specified the make and model of the AP.

I have never used wicd, but several people on the openSUSE forums abandoned it because it was buggy. Are you sure it is not the problem?

hello larry,

i've an ALFA AWUS036NHR and i tried latest compat-wireless-2011-09-27 on ubuntu natty 3.0.4-030004-generic,
the adapter is recognized as rtl8192cu but is not
responding, no network is detected.

Then if i try to "modprobe -r rtl8192cu" results
FATAL: Error removing rtl8192cu (/lib/modules/3.0.4-030004-generic/updates/drivers/net/wireless/rtlwifi /rtl8192cu/rtl8192cu.ko):
Device or resource busy

seems that remains blocked..i can't do anything

Hello,

I also have the AWUS036NHR device and I got it working on Ubuntu 11.04 2.6.38-11-generic x64. The only thing I did is to compile&install compat-wireless-2.6.39-1 (same as beini!) which can be found here:
http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.39/

There was only one strange thing: In drivers/net/wireless/rtlwifi/rtl8192cu/sw.c there is no entry for the AWUS036NHR so that no driver is loaded when I plugged the USB in, but in older versions of compat-wireless (e.g. 2.6.38) there IS one entry for this device. The entry looks like this:

/* 8188RU in Alfa AWUS036NHR */ {RTL_USB_DEVICE(USB_VENDER_ID_REALTEK, 0x817f, rtl92cu_hal_cfg)}

So I patched the file, compiled&installed it and everything worked! Could someone patch the sources and add this device? Thanks!

Hello Larry,

thanks for the quick reply! Yes I know this version is a bit older, but when I use the newest compat-wireless (eg.
http://www.orbit-lab.org/kernel/compat-wireless-2.6/compat-wireless-2011-10-07.tar.bz2)
the driver loads but some features like monitor-mode and packet injection doesn't work. The listing of available networks (with airodump) doesn't work too. Usually I have 13 channels because I live in Germany but if I use the newest driver I have only 11 channels. But if I use the older compat-wireless package all works fine.

The difference between 11 and 13 channels depends on your CRDA settings. Do you have that package installed? Check the output of dmesg to see what domain is being set. If you have CRDA installed, then you can force the use of Germany in the domain by creating a file named /etc/modprobe.d/50-cfg80211.conf containing a single line with "options cfg80211 ieee80211_regdom=DE" (without the quote marks).

You can get a list of available networks using iwconfig or iw. I know those work.

As I do not test, support, nor condone packet injection, I cannot speak to it working on any driver.

Sorry, but i can't get this Alfa product to work with the latest bleeding edge compat-wireless-2011-10-08 on ubuntu 11.04, tryed with kernels 2.6.38-11, 2.6.39 rc4 and 3.0

i tryed also the 2.6.39-1 version of compat-wireless

Don't show anything in managed and monitor mode..

i've tried also kernel 3.1-rc9 with latest compat wireless 14-10-2011 and still don't work...it was recognized but no APs can be detected..the led of the alfa is off..seems that it is power off..

i don't know about firmware, i see that there are .bin on lib/firmware/rtlwifi..
how can i update them?

ok, i've attached the alfa and run rfkill list but it shows that there are no blocked devices, then i run modprobe rtl8192cu and strangely the alfa has lighted, but it doesn't work..
i've done dmesg and seen this:

for the firmware i don't know how to update it, i'm using ubuntu 11.04 natty with 3.1.0-0301rc9-generic
where can i download updated firmware to test it for this card? thx

ok, i've checked the md5 checksum of the firmware and is ok, i give you dmesg at pastebin.com

it has 2 parts: in the second part i can't see what is in previous of the error

the link is: http://pastebin.com/7tfcBfbD

i tested the compat wireless drivers with another alfa awus036h and it works well, i tested also the realtek linux drivers 8192cu and the alfa awus036nhr works with them in the same distro and same kernel
with rtl8192cu and xhci_hcd there are these no room on ep ring errors :(

yes, i know that the awus036h uses a different driver, i just wanna say that it
has no conflicts with xhci_hcd as happen when loading the rtl8192cu driver for the 036nhr

the driver i downloaded from realtek is what you can find here
http://www.alfa.com.tw /in/front/bin/ ptlist.phtml?Category=105397 for the awus036nhr, and it works fine without any kind of errors,
detection of APs and connections

every compat wireless i download does not with rtl8192cu and my alfa, i tested all the specific kernel version of compat-wireless and the latest bleeding edge compat wireless, i'm hating this fuckin errors :)

i don't know why you are saying this, i was just kidding.... you take me too seriously...
i think i'm doing a favour to you too debugging this..

however with the rtl8192cu the hardware doesn't work with the ep error related to xhci_hcd..
it is the point that we are now

there is something more can i do now?
i don't have any other usb port that works with other controller like ehci..

ok, i've done what you asked me with usbmon,
but i'm not sure that is what you want

i've redone dumping dmesg trying to grab the information you are lookin for

i can't upload it on pastebin cause it's too large, i uploaded logs on megaupload

http://www.megaupload.com/?d=3D0QS1MX

i'm sorry but i don't know how to recompile kernel to apply this patch, i'm using the 3.1.oneric.rc9 for ubuntu precompiled
can u recompile it with this patch,
and then send me the compiled kernel to install?

Is there a way to set the tx-power over 20dbm on the adapter?
I thought it is able to do 2w. There is no way for me to get it over 20 dbm. When trying to to set the adapter with "iwconfig wlan1 set txpower 30" it answers

Error for wireless request "Set Tx Power" (8B26) :
SET failed on device wlan1 ; Invalid argument.

I think there has to be done some work in the code but where do I start?

Thanks for all replys.

The WEXT interface is deprecated. It is there as a convenience, but it will not be extended. To change the power setting, you need to use the iw utility. The specific commands are:

iw dev <devname> set txpower <auto|fixed|limit> [<tx power in mBm>]

or

iw phy <phyname> set txpower <auto|fixed|limit> [<tx power in mBm>]

The maximum power will be dependent on your regulatory domain setting.

Did you tested the commands you posted to me? Anyway here they do nothing. I cant see any changes in iwconfig nor in in iw.

iw reg get
country 00:
(2400 - 2494 @ 40), (N/A, 33)
(4910 - 5895 @ 40), (N/A, 33)

so after my regulatory domain I should be able to change the adapter settings.
